To all 'whom t may concern Be it known that l, THOMAS A. DE Vn,- niss, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Chio, have invented a certain new and useful Combined Aspirating and Vaporizin Instrument; and I do hereby de` clare the ollowing to be a full, clear, and exact description of the invention, such as will'enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings and to the characters of reference marlred thereon', which form a part of this specification.

This invention relates to medical appliances, and particularly to an instrument which combines the actions of both a vaporizing instrument and an aspirator.

The object of my inventlon is the provision of a simple and efiicient appliance, more particularly, but not necessarily, for use by the medical profession, which appliance combines an aspiratorand a spraying or vaporizing means capable of use together, whereby, for instance, matter in liquid or powder form may be sprayed into one nostril of the nose and a suction or aspirating action at the same time set up in the other nostril, or the two devices may be used separately, if desired. y

A further object of my invention is the provision of means for relatively adjusting the ejecting and suction nozzles of the 1nstrument to facilitate a reversal of the treating, cleaning or irrigating action within the nasal passages. Further objects and advantages of the invention will be apparent to persons skilled in the art from the follow-v ino' detailed description.

he invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings in connection with a liquid atomizing instrument, in which drawin Figures 1 and 2 are di'erent si' e elevations of an instrument embodying the invention. Fig. 3 is a section on the line 3 3 in Fig. l, with the suction nozzle turned down, and Fi 4 is a section on the line 4--4 in Fig. 8, wit the aspiratornozzle also in section.

'Referring to the drawings, l designates a receptacle, the upper open end of which is nclosed by a head 2, which head, in the preswith its passage in register with the lower end of the head passage 5. The outer ends of the passages 5 and 6 have communication respectively with thc passages in a pair of tubes 8 and 9, respectively, which are carried by and project, in the present instance, transversely from the head 2 one within the other. The outer end of the tube 8 terminates within the outer end portion of the tube 9 in register with a restricted discharge orifice 10 therein whereby the discharge of air from the tube 9 through said orifice around the discharge end of the inner tube 8 will tend to set up a suction action within the tube 8 so that liquid is drawn from the interior of the receptacle l through the tube 7 passa e 5 and tube 8 and discharged from the nozz e ends of the tubes 8 and 9 in vapor or spray form, as is common in liquid atomizin'g instruments. 11 designates a nasal tip which is secured to the outer end of the tube9.

Air under pressure is introduced into the receptacle l through a tube l2, which has connection with any suitable source of air .pressure supply and is connected at one end to a heel piece 13 projecting transversely from the head 2 with the passage thereof in communication with the passage 4.

It is thus evident that air under pressure may be introduced into the receptacle 1 through the passage l and cause a compressing action to be set up on the top of the liquid withinthe receptacle and a consequent forcingof the liquid out through the tube 7, passage 5 and tube 8. A portion of the air within the receptacle escapes therefrom 'through the passage 6 and tube 9 and is discharged from said latter tube, past the discharge end of the liquid tube 8 to set up a suction therein, as hereinbefore described, whereby to assist the compressive action "by a tube?, which is carried by the head 2 Lacasse within the receptacle in discharging the liquid in vapor-ized form from the receptacle. The air outlet passage 6 is smaller in size than the air inlet passage Il; so as to utilize a portion of the air introduced into the receptacle for compressing the liquid. A valve 11 threads down through the head 2 and has its lower end seating in a portion of the passage 4 to close the communication through said passage between the heel-piece 13 and the interior of the receptacle. i

head 15 is carried by the tube 9, being tixedly secured thereto, in the present in stance, by a set-screw 16, and a receptacle 17 is removabl)7 carried by said head, being, in the present instance, threaded into a socket in the lower end thereof. A tube 18, in the present instance of Z-torm, has its inner end rotatably connected to the forward side of the head 15, as by fitting into a soclreted part 19 thereof and communicatin with the interior of the receptacle 1 through an angled passage 2O in said head. The tube 18, which may be termed a suction tube, is preferably attached to the head 15 below the tube 9 so that the outer end of the tube 18, which carries a nasal tip 21, may

be positioned at either side of the nasal tip 11 as it may be desired to insert the tip 11 into either nostril of the nose and the tip 21 into the other nostril thereof.

A tube 22 connects the two heads 2 and 15 and has communication at one end with the passage in the heel-piece 13 through a passage 23 of annular form provided in the head 2 around the passages 4, 5 and 6. 'llhe other end of the tube 22 has communication with a pair of opposed air discharge oriices 2e disposed transversely in the head 15 with their outer ends opening to the at mosphere through enlarged passages provided in discharge plugs or nozzles 25, which are threaded into opposite sides of the head 15. The air in its discharge from the passages 24 plays across the adjacent ends ot passages 26, which project transversely trom the passages 2e into communication with the interior of the receptacle 17 at its upper end, and cause air to be drawn or exhausted from the interior ot the receptacle 17.. lt is evident Athat the exhaust ot air "from the receptacle 17 through the passages 26 and nozzles 25 will canse an inward suction to take place thrcugh the tube 18, thereby causing it to act in the manner of an aspirator. lt will be noted that the passages E21, 24 and the passages in the nozzles 25 longitudinally aline so that a wire may he inserted. entirely through said passages tor cleaning pun poses.

ln the use oi my appliance for the treatment et nasal trouhles, tor instance, catarrh, cold in the head, or the like, the tip en the discharging insane 's inserted inte one nostril et the ness, tip 21 or the aspirating device is inserted into the other nostril of the nose, and air pressure then turned into the instrument through the supply tube 12. The valve 14 being open permits a portion of such air under pressure to enter the receptacle 1 through the passage 4 and to act on the liquid within the receptacle to :torce it therefrom through the tubes 7 and S and passage 5 and also to pass in part through the outlet passage 6 and air tube 9 and be discharged from the tip 11 together with the liquid which is forced and drawn from the receptacle 1 in a vaporized thoroughly broken-up condition, as is well understood in the art. A port-ion of the compressed air also passes through thev restricted discharge oriices 24, 2a in the head 154over or past the passages 26, which communicate with the receptacle 17, thus exhausting air from said receptacle and setting up a suction action therein through the tube 18. It is thus evident that a vapor-ized liquid is discharged into one nostril of the nose by the liquid atomizing or vaporizing means, and that liquid and other matter is drawn from the other nostril of the nose and deposited in the receptacle 17, thereby eitecting a thorough cleaning, cleansing and irrigating of the nasal passages. After a cleansing action has been effected in one direction through the nasal passages the position ot the aspirator tuhe 21 is reversed with respect to the tip 11 so that a reverse circulation can be set up within the nasal passages.

it is desired to use the aspirator alone the valve le may be moved to close the air inlet passage l to the receptacle 1; or if it is desired to use the atomizing attachment alone the aspirator tube 18 may be swung to 1 a position which will not interfere with the use or the atomizer nozzle.

lWhile l have shown my aspirating attachment as used in connection with an atomizer, it is not intended to restrict its use in this respect, as the means illustrated herein as forming a liquid vaporizing means might be an atomizer, nebulizer, or a powderblower wherein a liquid or powder is discharged from the receptacle by the action ot air, it being understood that the invention broadly contemplates the utilization in a single instrument of a iiuid under pressure for creating an aspira-ting action in one part thereof, and a matter discharging action in another part thereof.

also wish it understood that my invention is not limited to any specific construction, arrangement or torni of the parts. as

is capable ot ,numerous modications without departing from the spirit ot the invention dened in the claims.
